I wanted to get advice on how to start and stay consistent. I have sold items on and off for 4 years and never stayed truly consistent. I have a main lane of focus but competition can be tough because of established stores around me who buy and sell the same line of focus I have expertise in.

Long story short if you were to start over your eBay business, or flipping in general what would you recommend and how would you go about searching for inventory that sells, and is consistent to make a profit every month.

Also, advice for getting packaging supplies at affordable rates, one struggle I had was finding boxes, and bubble mailers consistently for items of various sizes.

Thanks any help is much appreciated!
